The invention relates to an inflatable flexible energy absorption assembly. The inflatable flexible energy absorption assembly comprises an anti-collision cross beam and at least two energy absorptionunits connected to the anti-collision cross beam; the inflatable flexible energy absorption assembly further comprises an inflation unit; the inflation unit is communicated with the energy absorptionunits so as to inflate the energy absorption units with a gaseous energy absorption medium. Each energy absorption unit comprises an outer skin, a constant pressure valve and a safety valve so as toabsorb energy through compression of the energy absorption medium, wherein the outer skin provides a cavity for accommodating the energy absorption medium, the constant pressure valve is a one-way valve communicated with the inflation unit so as to fill the energy absorption medium with set pressure into the cavity, and the safety valve is a pressure release valve communicated with the atmosphere.According to the inflatable flexible energy absorption assembly, two traditional energy absorption media of EPP foaming and plastic are abandoned, the compressed gaseous energy absorption medium is adopted for buffering and energy absorption, meanwhile, the concept of the modular energy absorption units is provided, and the two-way purposes of weight reduction and cost reduction can be achieved while the energy absorption efficiency is improved.

    本发明涉及一种充气式柔性吸能总成,其包括防撞横梁和连接在防撞横梁上的至少两个吸能单元,还包括充气单元,充气单元与吸能单元连通以向吸能单元充入气态的吸能介质,每个吸能单元包括外皮、定压阀和安全阀以通过吸能介质的压缩进行吸能,其中,外皮提供容纳吸能介质的空腔,定压阀为与充气单元连通的单向阀以将设定压力的吸能介质充入空腔,安全阀为与大气连通的泄压阀。根据本发明的充气式柔性吸能总成,颠覆了传统的EPP发泡和塑料这两种吸能介质,采用压缩气态的吸能介质进行缓冲吸能,同时提出了模块化吸能单元的概念,在提高吸能效率的同时,可实现减重和降本的双向目标。
